Features

Environment-centric configuration was implemented. Each microservice has both application.yml and application-docker.yml files. All components have been Dockerized. Running it in a Docker environment ensures the application-docker.yml configurations are applied.

Micro Services:

• KredinBizde Service:

  • Supports auditable entity classes.

  • Utilizes caching to improve performance by storing frequently accessed data in memory.

  • Utilizes Feign Client for communicating with the Garanti Service to create applications.

  • Implements asynchronous notification using RabbitMQ to send notifications.

  • Implements logging with Kafka to collect exceptions and stores them in MongoDB for further analysis and monitoring.

  • Implements custom exception classes to handle various error scenarios

  • Includes unit tests to ensure the correctness and reliability of the codebase.

    All unit tests successfully run:

• Garanti Service:

  • KredinBizde Service integrates with the Garanti Service for synchronously communicating applications from KredinBizde Service to the Garanti Bank.
  • Implements custom exception classes to handle various error scenarios

• Notification Service:

  • Implements the Strategy Pattern to provide a flexible and extensible way of sending notifications.
  • The Strategy Pattern allows to support multiple notification strategies (e.g., email, SMS, mobile) and switch between them dynamically at runtime.

• Log Service:

  • Responsible for generating exception logs and storing them in MongoDB using Kafka for message queuing.

Service Registry:

• All above services should Register them with this Registry

API Gateway:

• All Services should be accessible with single gateway

Docker

All Kredinbizde microservices and related components are collected in docker-compose.yml. Applications were containerized. This build can be easily started with the docker-compose up command. Once all services start running in Docker, you can access Swagger from here.
